A strange 200 million-year-old object with the mass of a planet has been discovered 20 light-years from Earth, outside our solar system. The "rogue," as it's referred to by researchers, is producing an unexplained glowing aurora and travels through space alone, without a parent star. The object, named SIMP J01365663+0933473, has 12.7 times the mass of the gas giant Jupiter, the largest planet in our solar system. It also has a strong magnetic field that is more than 200 times stronger than Jupiter's. The temperature on its surface is more than 1,500 degrees Fahrenheit. There seems to be a non fusion heat source that is keeping these planets down to the size of asteroids internally active. Could it be metallic hydrogen? NASA is going to look for a liquid ocean inside the asterod Ceries. https://www.cnn.com/2018/08/07/world/rogue-planet-beyond- solar-system-trnd/index.html Is cryovolcanism active on Ceies today?
